[rules-users] Mavenizing a new drools project

[eyal edri]

OK, Still got problems.

i've created a maven project, and all looks good in compile time (with all
the org.drools dep below).

but i think i still missing a 'runtime' dependency, cause when i try to run
the Hello World example, i get this error:

[the src line is this:
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();]

org.drools.ProviderInitializationException: Provider
org.drools.builder.impl.KnowledgeBuilderProviderImpl could not be set.
